RepositoryItemTrackBar.SmallChange Property

Gets or sets a value to be added to or subtracted from the TrackBarControl.Value property when
scrolling using the keyboard arrow keys (and the mouse wheel, provided that SmallChangeUseMode is set to ArrowKeysAndMouse).

The SmallChange property can be set to a percentage of the Height (for a vertically oriented track bar) or Width (for a horizontally oriented track bar) value. This keeps the distance your track bar moves proportionate to its size.

Set the SmallChangeUseMode property to ArrowKeysAndMouse to allow the control to be additionally scrolled by the SmallChange amount when using the mouse wheel.
